That's sort of my take. Super wealth comes from founding or having a large stake in a unicorn. That's of course true but also rare and sort of like a kid betting his future on playing in the NBA. Sure some people make it, but the vast majority do not.

"Enough" wealth -- i.e. retiring with millions in assets, is much more attainable by anyone who simply invests sensibly over the course of a working career. You don't even need stock options or equity compensation or a SV salary.
